Insulated Garden Rooms for Leatherhead Properties
Adacon supplies the P600 modular building system, a high-specification steel-framed solution for homeowners seeking extra space. Each module provides approximately 13 m² of floor area and is delivered to your site in Leatherhead fully finished internally with plastered walls, laminate flooring, and integrated electrics. Because these are not shipping container conversions, they offer the aesthetic and thermal performance of a permanent building while maintaining the flexibility of a modular install.
Typical Configurations and Sizes
The P600 system is inherently flexible, allowing you to choose a layout that fits your specific garden dimensions and functional needs. Our garden rooms serve a variety of purposes, from professional workspaces to leisure facilities.
Single Module (13 m²)
Ideal for a generous garden office or a private treatment room. A single P600 module (approx. 6m x 2.4m) provides ample space for a desk, seating, and storage, making it a popular choice for properties with standard garden footprints in residential areas like Fetcham or Bookham.
Double Module (26 m²)
By joining two modules side-by-side, we create a substantial 26 m² space. This configuration is frequently used for home gyms, large hobby rooms, or guest annexes. The internal finish is seamless, providing a wide-span interior that feels like a traditional room.
Multiple and Two-Storey Units
For larger plots or specific requirements, modules can be arranged in L-shapes or stacked over two storeys with internal staircases. This is an efficient way to maximise floor area without losing significant garden space, subject to local site conditions and planning considerations.
What is Included as Standard?
Every Adacon garden room is built to a high specification to ensure year-round usability. The standard package includes:
- Fully insulated floor, walls, and roof for thermal efficiency.
- Plastered and painted internal walls and ceilings.
- High-quality laminate flooring.
- LED lighting and multiple power sockets.
- Double-glazed uPVC windows and external doors.
- Exterior cladding in a range of colours, which can be selected wall-by-wall via our configurator/p600.
Optional extras include WC and shower compartments, kitchenettes, air conditioning, and external decking to integrate the building into your landscaping.
Indicative Pricing in Leatherhead
For residential garden uses, prices typically range from £15,000 to £35,000 depending on the number of modules and the complexity of the internal fit-out. A single-module garden office with standard finishes represents the lower end of this range, while multi-module buildings with added plumbing or bespoke cladding sit at the higher end. These figures are indicative; we recommend using our online tools for a project-specific estimate.
Delivery and Installation to Leatherhead
Leatherhead sits in a prime location for logistics, typically accessed via the M25 (Junction 9) and the A24. Our modules are transported by HGV and usually positioned using a HIAB crane. For projects involving modular buildings in Leatherhead, we consider the local geography, such as the narrow residential roads near the town centre or the more rural access lanes toward the Surrey Hills.
It is the customer's responsibility to ensure a level, prepared base is ready for delivery. Groundworks and final electrical connection to your home's consumer unit must be carried out by local qualified contractors. Our team can provide the necessary technical drawings to assist your local tradespeople in preparing the site.
Planning Permission and Building Regulations
Many garden rooms fall under Permitted Development, but this is never a guarantee. Rules vary significantly depending on the size of the building, its position relative to your property boundary, and whether your home is in a Conservation Area or a restricted zone. We strongly advise all customers in the Leatherhead area to check with the Mole Valley District Council planning department before commencing work. Similarly, if the building is intended for sleeping accommodation, it will likely need to meet specific Building Regulations.
Why Adacon?
We provide a faster, cleaner alternative to traditional building methods. Our lead times are measured in weeks rather than months, and because the majority of the work happens in our production facility, on-site disruption is kept to a minimum. Our steel-framed construction offers a level of structural integrity and longevity that timber-framed 'log cabins' simply cannot match.
